By default Rich Text Editor maps most special characters to the equivalent HTML entity automatically. You can turn it off by setting this property to "false".
<% Dim rte Set rte=new RichTextEditor rte.Text="Type here" rte.UseHTMLEntities=false rte.ID="Editor1" rte.MvcInit() Response.Write(rte.GetString()) // use Request.Form("Editor1")to retrieve the data %>
